libroken: Rename static pidfile_path to rk_pidfile_path
This is odd because libroken uses pidfile(3) AND it's own pidfile system.
So potentially it's managing two pidfiles.
libutil.h owns the pidfile namespace (other OS expose other names which
may conflict) so rename the local vars to rk_pidfile_*.
pidfile: Add functionality for use in sandboxing
pidfile_fd() returns the file descriptor of the locked pidfile so it can
be limited in sandboxes like Capsicum.
pidfile_unremoveable() will avoid unlink(2) being called at program exit
to avoid tripping any sandboxes like Pledge which may restrict it or
it's just not reachable anymore if the program is in a chroot(2).
pidfile_path() returns the path of the locked pidfile so it can be removed
by a process than can reach it if pidfile_unremoveable() has been called.
pidfile_unlock() just releases the resources held by the locked pidfile.
This is lighter weight than pidfile_clean() as it avoids a lseek and read.
- Reduce delays for MII access.
- Fix multicast filter setup (and thus IPv6).
- Align MAC address setup code with other drivers.
- Create bus_dma map with BUS_DMA_ALLOCNOW to prevent failures
when loading the map.
eqos: More performance improvements.
- Move TX to a separate kthread and allow TX and RX to run under separate
locks. Lazily clean up TX descriptors instead of requesting an interrupt
for TX completions.
- Use the hardware watchdog to implement RX interrupt coalescing.
- Remove some redundant MMIO writes and bus_dma syncs.
mi pmap: capture PTE (HW updated) referenced and modified bits
When removing a page mapping or changing its protection capture any
HW updated referenced and modified bits.
musescore: correctly report this as a "release" build
The exact CMake arguments had changed over time, and this was missed in
the update to 4.x.
While here, also drop another argument that has no effect. There is a
newer way of requesting the same, but we're not actually building that
way anyway at present, and enabling it leads to other troubles with Qt6
stuff.
